Referring to FIGS. 1F and 1G, the host mobile device 110 (not shown) can be inserted or locked in between the guides 165 of the middle portion 153. Although some embodiments contemplate a via in the mobile device cover 100 through which a female connector (e.g., a female USB-type connector) of the host mobile device can be accessed, other embodiments contemplate the mobile device cover 100 with a connector 175 (e.g., a lightning connector, a USB-type connector, a data connector, a recharging connector, multi-pin connector, etc.) that mates with the female connector of the host mobile device 110 to provide a connection (e.g., a power connection, a physical connection, an electrical connection, a signal connection, a synchronization connection, etc.). In some embodiments, the connector 175 provides a connection (e.g., electrical connection, data connection, etc.) between circuits in the host mobile device 110 and the mobile device cover 100. For example, the batteries in the host mobile device 110 and the mobile device cover 100 can charge each other via the connector 175 and/or other ports, for example. In some embodiments, the connector 175 is part of a connector assembly that includes a connector element 148, a coupler 149, and a port 147. In addition to or instead of the connector 175, the host mobile device 110 and the mobile device cover 100 can communicate wirelessly (e.g., Bluetooth communication, near field communication (NFC), other radio frequency (RF) communication (e.g., Wi-Fi), infrared communication, Zigbee communication, wireless personal area network (PAN) communication, IEEE 802.11 communication, etc.) with each other, as mentioned below. In some embodiments, the front side 145 of the mobile device cover 100 can be interlocked with the middle portion 153 of the mobile device cover 100 with the host mobile device 110 there between. As noted before, the main display of the host mobile device 110 may or may not be covered by a transparent material of the mobile device cover 100. In some embodiments, a window 195 is provided in the front portion 145 of the mobile device cover 100 so that the user can directly touch the display (e.g., touch-sensitive screen) of the host mobile device 110.

In some embodiments, the mobile device cover 100 can be an accessory to the host mobile device 110. In some embodiments, the mobile device cover 100 can be an accessory that is operable while separate from the host mobile device 110. The accessory can be in wireless communication with the host mobile device 110. In some embodiments, the mobile device cover 100 and the host mobile device 110 can be controlled via inputs (e.g., buttons, touch-sensitive screens, capacitive touch, sliders, graphical elements on graphical user interfaces, etc.) located on the mobile device cover 100, the host mobile device 110, a mobile application running on the host mobile device 110, a mobile application running on the mobile device case 100, a wired and/or wireless signal sent to the host mobile device 110, a wired and/or wireless signal sent to the mobile device cover 100, etc. The wireless signal can include, for example, Bluetooth signals, IEEE 802.11 signals, wireless local area network (WLAN) signals, wireless personal area network (PAN) signals, Zigbee signals, infrared signals, RF signals, etc. sent to the mobile device cover 100, the host mobile device 110, etc. Accordingly, the mobile device cover 100 and/or the host mobile device 110 include, for example, antennas and circuits (e.g., processors, wireless hardware, transceivers, transmitters, receivers, etc.) to support wireless communication between them 100, 110, and/or between the mobile device cover 100, the host mobile device 110, and/or other wireless devices (e.g., wireless speakers, wireless microphones, wireless headphones, wireless earbuds, wireless displays, base stations, access points, wireless networks, etc.).

Referring to FIG. 1A, a back side 158 of the back portion 155 (e.g., back cover) of the mobile device cover 100 is shown. The back portion 155 of the mobile device cover 100 has lights 160. The lights 160 can form, be a part of, and/or illuminate a screen (e.g., a main screen or display, indicator lights, light patterns, etc.) and can emit different colors with different intensities at different times. The lights 160 can also form, be a part of, and/or illuminate another screen 132 or an extension of the main screen along an edge 130 (e.g., a beveled edge, a chamfered edge, a side, a lateral side, a border of the screen 162, etc.) of the mobile device cover 100. Further, the lights 160 can illuminate beads 180 with different colors as indicator lights, for example. The beads 180 can be colored or not, and can be at least partially transparent, for example. In some instances, the beads 180 can take the configuration of letters, numbers, and/or shapes and can be flat or raised in structure. The beads 180 can be used as part of a Braille reader system, for example. In some instances, the beads 180 can include, for example, LED or light covers. In some examples, the beads 180 can be flat transparent plastic windows that can be positioned over lights 160. In such an instance, the beads 180 can be colored, and/or the lights 160 can provide color through colorless, transparent beads 180. In some embodiments, the beads 180 can be disposed throughout the back cover 155 of the mobile device cover 100 so that the beads 180 can be illuminated in particular colors, patterns, and/or intensities at particular times and/or in response to certain alerts or other information (e.g., digital signals, digital data, analog signals, etc.) received from the host mobile device 110.

In some embodiments, when the host mobile device 110 and the mobile device cover 100 are operatively coupled, the mobile device cover 100 can provide indicators and/or data (e.g., digital data, video data, streaming data, etc.) from the host mobile device 110 to the user via output interfaces (e.g., lights, screens, speakers, etc.) of the mobile device cover 100. In some embodiments, when the host mobile device 110 and the mobile device cover 100 are operatively coupled, the mobile device cover 100 and the host mobile device 110 are in one- or two-way digital and/or analog data communication. The mobile device cover 100 can display information, data, and/or content (e.g., multimedia content, video content, streaming content, social media content, scrolling text, etc.) received from the host mobile device 110. Further, the host mobile device 110 can display information, data, and/or content received from the mobile device cover 100. The host mobile device 110 and/or the mobile device cover 100 can cause information, data, and/or content to be displayed on the host mobile device 110. Further, the host mobile device 110 and/or the mobile device cover 100 can cause information, data, and/or content to be displayed on the mobile device cover 100. The information, data, and/or content can be received from the host mobile device 110, the mobile device cover 100, another device, and/or a third party, such as a mobile application, a website, etc. FIG. 1E shows an embodiment of the mobile device cover 100 in which the back cover 1030 includes the lights 160 forming a touch-screen display 162 that can be similar or the same as the display that can be shown on the main display of the host mobile device 110. Thus, for example, the touch-screen display 162 of the mobile device cover 100 can operate in a same or similar manner (e.g., same or similar graphical user interface, graphical elements, touch-and-feel, etc.) as the main display of the host mobile device 110. The touch-screen display 162 of the mobile device cover 100 can provide the same or similar array of icons 164 as the main display of the host mobile device 110, for example, or can be completely different. This can be useful, for example, if the display of the host mobile device 110 is being used for another purpose (e.g., playing a video, taking a call, work use, personal use, etc.), but the user wants to access other mobile applications. For example, the host mobile device 110 can be used to operate a GPS navigation application, while the mobile device cover 100 is being used to watch a movie or to stream video. Further, since the host mobile device 110 and the mobile device cover 100 can be in wireless communication, the mobile device cover 100 can be detached from the host mobile device 110 while watching the movie or streaming video, for example.

Referring to FIG. 1A, when the host mobile device 110 is receiving an incoming call, for example, beads 180 that form the word “CALL” on the back cover 155 of the mobile device cover 100 can be illuminated, caused to flicker, flash, etc. If a calendar event notification is activated or received by the host mobile device 110, for example, the beads 180 that form the word “ALERT” can be illuminated, caused to flicker, flash, etc. If a text message is received by the host mobile device 110, for example, the beads 180 that form the word “TEXT” can be illuminated, caused to flicker, flash, etc. These events and others (e.g., social media postings or messages, changes in sports scores, news items, emails, SMS messages, etc.) can also be displayed on the touch-screen display 162. The beads 180 can also be illuminated different colors and with different intensities to indicate different degrees of urgency. For example, if the alert is urgent (e.g., an email sent with “high importance”), the beads 180 that form the word “ALERT” can flash red and/or with increased intensity to indicate urgency. In another example, if the incoming call or text message is not from an important person, which can be designated via programming, user settings, user configurations, user preferences, etc., the corresponding beads 180 can be illuminated a dim blue. In some embodiments, the mobile device cover 100 can determine the identity of the caller or the message sender via electrical signals, sound signals, acoustic signals, wireless signals, digital signals, etc. received from the host mobile device 110. In some embodiments, the host mobile device 110 can determine the identity of the caller or the message sender and send a data signal corresponding to and/or identifying the caller or the message sender to the mobile device cover 100 as well as other information (e.g., voice mail, text message, indications of importance, etc.). Further, the user may be notified as to the name, number, email address, etc. of the sender or source of the alert, text, email, or other notification via the lights 160, beads 180, or other output devices (e.g., speakers, screens, vibration, etc.) of the mobile device cover 100.

In some embodiments, the mobile device cover 100 can be configured to provide video (e.g., live streaming video, streaming video, stored video, etc.) and/or other information (e.g., digital data, messages, news, alerts, etc.) on one or more screens. The video can be provided via the host mobile device 110, for example, or some other source to which the mobile device cover 100 and/or the host mobile device 110 is operatively coupled. For example, the mobile device cover 100 can have its own wireless link with an access point (e.g., an IEEE 802.11-compliant access point) or a base station (e.g., a cellular base station, a portable base station, etc.) from which to download media content. The mobile device cover 100 can also include memory storage (e.g., non-transitory memory storage, solid state memory storage, removable memory sticks, disks, cards, etc.) on which resides media content for playing or displaying on the screen of the mobile device cover 100 and/or the host mobile device 110. The video can be, for example, stored on the host mobile device 110 or can be streamed via a wireless link (e.g., cellular link, WIFI link, IEEE 802.11 link, wireless local area network (WLAN) link, Bluetooth link, RF link, etc.) with a content provider or a third party application. In some embodiments, closed captioning or subtitles can scroll along the main screen 162 which can include and/or be supplemented with one or more screens 132 on one or more edges 130 of the mobile device cover 100. In some embodiments, the mobile device cover 100 can be configured to provide an alert of a received video message and to play the video message on the screen 162 of the mobile device cover 100. The screen 162 of the mobile device cover 100 can be substantially independent or can substantially mirror the screen of the host mobile device 110. The screens 162, 132 can be incorporated into the housing of the electronic device. Further, the screen 162 of the mobile device cover 100 can be touch-sensitive and employ graphical elements of a graphical user interface. Thus, for example, a user input via the touch-sensitive screen 162 of the mobile device cover 100 can provide a user input to the host mobile device 110 and/or the mobile device cover 100. The screen of the mobile device cover 100 can be set up to substantially mirror the screen of the host mobile device 110 or to operate independently of the screen of the host mobile device 110. Content or material can also be displayed on the mobile device cover 100 and/or the host mobile device 110 that is from an application on the host mobile device 110, for example. For example, if the user has access to a sports application running on the host mobile device 110 that shows sports videos, television channels, movie channels, or live events on the host mobile device 110, the video may be displayed on the host mobile device 110 and/or the mobile device cover 100.

Some embodiments provide that digital signals can be received or provided by the host mobile device 110 and forwarded to the mobile device cover 100 for storage, processing, and/or output (e.g., on a display, lights, a speaker, a vibrating mechanism, etc.). For example, in addition to multimedia data, some embodiments provide that data (e.g., alphanumeric data, indicators, control data, source information, etc.) can be received or provided by the host mobile device 110 and forwarded to the mobile device cover 100 for storage, processing, and/or output. For example, the edge screen 132 (or any other light 160 screen on the mobile device cover 100) can be configured to scroll information relating to news, sports, live or recorded events or movies, stocks, weather, calendar events, text messages, alerts, email, social media messages (e.g., messages or posts from mobile applications or websites such as Facebook, Twitter, Snapchat, Instagram, etc.), etc. In some embodiments, the information can scroll around one or more edge screens 132 around the mobile device cover 100. In some embodiments, the host mobile device 110 can be set to periodically receive or retrieve sports data (e.g., scores, news items, etc.) or other types of data. The data can be from, for example, websites, mobile applications, other host mobile devices, etc. The host mobile device 110 can send sports data, for example, to the mobile device cover 100; and the mobile device cover 100 can display or scroll the data across the edge screen 132 of the mobile device cover 100 or display or scroll on the screen 162. In some embodiments, the edge screen 132 can be touch-sensitive, thereby allowing the user to tap, toggle, or swipe (or some other user input) an email notification and read a scrolling email on the edge screen 132 or on another display (e.g., the main display 162 on the back cover 155) of the mobile device cover 100. In some embodiments, the data can flow across the edge screen 132 in response to a finger sweeping motion along the edge touch-sensitive screen 132. In one embodiment, an incoming text message can be indicated by the beads 180 forming the word “TEXT” being illuminated by lights 160, the sender of the incoming text can be displayed on the edge screen 132, and the text of the text message can be displayed on the main screen 162 on the back cover 155 of the mobile device cover 100. In one embodiment, alphanumeric letters are displayed on the screen on the back cover 155 and the edge 130, either simultaneously or independently, indicating that a text message has been received and possibly displaying the sender's name, the sender's associated icon (e.g., icon, emoji, animated icon, animated emoji, etc.), the sender's associated image (e.g., sender's picture), the sender's subject, the sender's header, the sender's body text, the sender's partial or full text, etc. A text or email icon can be displayed instead of the words TEXT, for example. The display can also be a series of LEDs forming a grid to accommodate lights show, scrolling text, etc.

The edge screen 132 can be configured to scroll completely or partially around the mobile device cover 100 and/or along one or more of its edges 130. In some embodiments, the edge 130 can be segmented or partitioned so that the right edge portion is reserved for a first subject (e.g., stocks), the left edge portion is reserved for a second subject (e.g., sports), the bottom edge portion is reserved for a third subject (e.g., email), and the top edge portion is reserved for a fourth subject (e.g., calendar items, alerts, etc.), for example. Within each segment, the edge screen 132 can scroll the data. In some embodiments, the user can program and/or select which subject is displayed on each individual segment on the mobile device cover 100. In some embodiments, the user can program the mobile device cover 100 so that it decides on which segment to display a particular subject (e.g., incoming call, incoming text, incoming email, incoming message, mobile device notification, mobile device accessory notifications, music or other audio notifications, social media notifications, etc.).

FIG. 1B shows a top view of an embodiment of the mobile device cover 100 according to the present disclosure. FIG. 1C shows a partially exploded side perspective view of an embodiment of the mobile device cover 100 according to the present disclosure.

Referring to FIGS. 1B and 1C, the mobile device cover 100 can be adapted, for example, to provide physical vias (e.g., access openings and windows) through which various input interfaces and output interfaces of the host mobile device 110 can be accessed without detaching the mobile device cover 100 from the host mobile device 110. In some embodiments, the mobile device cover 100 may provide a physical opening to access a display, a camera, a button, a control, other input/output (I/O) interfaces, etc. of the host mobile device 110. In some embodiments, the mobile device cover 100 does not cover the main display of the host mobile device 110 when the mobile device cover 110 is attached to the host mobile device 110. In some embodiments, the mobile device cover 100 may provide a transparent or partially transparent cover portion, for example, over a display or other portions of the host mobile device 110. The transparent cover portion can be made of materials that, for example, do not interfere with the operation of any of the touch screens, speakers, and/or buttons of the host mobile device 110. In some embodiments, the materials can be substantially transparent to wireless communication links used by the host mobile device 110 and/or the mobile device cover 100. The transparent cover portion may also protect areas of the host mobile device 110 such as touch screens from scratches or other damage.

Some embodiments according to the present disclosure may provide that the mobile device cover 100 is made of one or more of the following materials: silicone, rubber, metal, plastic, polymers, polycarbonates, composites, cloth, metal, wood, acrylic, glass, plexiglass, and/or other materials. The cover material may be, at least in part, opaque or transparent. The cover material may assist a user in gripping the host mobile device 110 and may protect the host mobile device 110. The cover material may be, for example, one or more of the following: shock resistant, shock proof, shatter proof, shatter resistant, dust resistant, dust proof, water resistant, water proof, etc. In some embodiments, the mobile device cover 100 may be made up of multiple pieces (e.g., portions 100 a, 100 b, 100 c, one or more printed circuit boards, housings, etc.), as shown in FIGS. 1B and 1C. In some embodiments, the multiple pieces of the mobile device cover 100 interlock together to house, become the back panel of the host mobile device 110, and/or to connect (e.g., physically and/or electrically connect, snap, interlock, etc.) to the host mobile device 110.

Referring to FIGS. 1B and 1C, the mobile device cover 100 can include, for example, circuitry 150 and lights 160 disposed on one or more printed circuit boards. In some embodiments, the circuitry 150 can include one or more of the following: one or more processors, one or more non-transitory memories, signal processors, light control circuitry, light drive circuitry, battery recharging circuitry, battery control circuitry, display control circuitry, sensors, input interface circuitry, output interface circuitry, digital-to-analog converters, analog-to-digital converters, wired transceivers, wireless transceivers, input/output ports, input/output interfaces, and antennas. The one or more non-transitory memories can be configured to store, for example, data (e.g., input data, data received from the host mobile device 110, stored reference data, stored configuration data, stored personal data, etc.) and processor-executable instructions or code for use with the one or more processors. The circuitry 150 can be connected, for example, to and/or can include the lights 160. Some embodiments provide that the lights can include one or more of the following: LEDs, flexible active-matrix OLEDs (AMOLEDs), OLEDs, phosphor-based LEDs, white LEDs (WLEDs), multi-color WLEDs, semiconductor LEDs, other types of LEDs, LCDs, LCD touch screens, electroluminescence, pixel displays, etc., and can be arranged or used in a specific pattern, array, sequence, etc. Some embodiments provide that the lights can be raised or provide bumpy surfaces suitable for use in a Braille system. Various components and/or elements of the circuitry 150 can be connected to each other through one or more buses, for example.

The mobile device cover 100 can also include, for example, a battery 170 (e.g., a rechargeable battery, a non-rechargeable battery, etc.) that can be used to power, for example, the circuitry 150, the lights 160, and any other circuitry or components in the mobile device cover 100 and/or the host mobile device 110. The battery 170 can also be used to power the host mobile device 110 and/or to recharge a battery in the host mobile device 110. In some embodiments, the mobile device cover 100 does not have a battery and instead can be powered by the host mobile device 110. Some embodiments according to the present disclosure provide that the battery 170 can be rechargeable or not rechargeable. If not rechargeable, the battery 170 can be replaced. Some embodiments of the battery 170 include, for example, a lithium battery, an alkaline battery, a silver-oxide battery, nickel cadmium battery, nickel metal hydride battery, lithium ion battery, lithium ion polymer battery, etc. If rechargeable, then the battery 170 can be recharged, for example, by drawing energy from one or more interfaces of the host mobile device 110 (e.g., an audio port, an earphone jack, a docking port (e.g., a USB-type port, a lightning connector port, a power and signaling connection port, etc.), a wireless charging pad, etc.). The battery 170 can also be recharged by drawing energy separate from or independent of the host mobile device 110. Similarly, a rechargeable battery of the host mobile device 110 can be charged through one or more interfaces of the host mobile device 110 that are electrically and/or wirelessly connected to the mobile device cover 100. The rechargeable battery of the host mobile device 110 can also be recharged by drawing energy separate from or independent of the host mobile device 110.

For example, independent of whether the mobile device cover 100 is connected to the host mobile device 110, the mobile device cover 100 and/or the host mobile device 110 can be separately plugged into a wall outlet or wirelessly charged at a wireless charging station. The mobile device cover 100 can also be charged by plugging it into a computer, a charger bank, a generator, etc. via a USB-type connection, for example. The battery 170 of the mobile device cover 100 can be charged by a piezoelectric battery charger, for example. In some embodiments, the piezoelectric battery charger can convert force (e.g., caused by pressure, movements, mechanical forces, etc.) into electrical energy for use by the battery 170. Some embodiments contemplate converting other types of energy (e.g., sound energy, light energy, electromagnetic energy, solar energy, magnetic energy, thermal energy, moving air, wireless energy, etc.) into electrical energy to charge the battery 170. For example, the mobile device cover 100 can be configured to convert solar energy to recharge its battery 170. In some embodiments, the mobile device cover 100 can utilize charging methods such as conductive and inductive charging.

In some embodiments, the battery 170 of the mobile device cover 100 can also be recharged when the host mobile device 110 is wirelessly or wiredly connected to a power source (e.g., AC and/or DC power source). For example, the battery 170 of the mobile device cover 100 can be recharged when the host mobile device 110 is connected to a wall outlet, for example, such as when a docking port of the host mobile device 110 is connected to a wall outlet. The battery 170 may receive energy directly from the wall outlet (e.g., via connecting the mobile device cover 100 directly to the wall outlet) or indirectly from the wall outlet through the host mobile device 110. In addition, the battery 170 may receive energy when a docking port or some other interface of the host mobile device 110 is connected to a computer while electrically and/or wirelessly connected to the mobile device cover 100. Some embodiments according to the present disclosure contemplate that the circuitry 150 receives power from the host mobile device 110 without using the battery 170 or in combination with the battery 170. Thus, some embodiments according to the present disclosure might not have a dedicated battery as part of the mobile device cover 100, or might use the battery 170 as a back-up power source.

In some embodiments, just as the battery 170 of the mobile device cover 100 can draw on energy from the host mobile device 110, the battery of the host mobile device 110 can draw on energy from the mobile device cover 100 to recharge the battery of the host mobile device 110 or to supplement power to the host mobile device 110. For example, as rechargeable batteries age, they are less capable of fully powering the main processor on the host mobile device 110. The aging batteries have reduced full charge capacity and provide less power, voltage, and/or current during normal operation. As a result, some processors (e.g., central processor, graphics processor, general processor, dedicate processor, etc.) will enter a power-save mode in which processor speed (e.g., clock speed) and/or load capacity (e.g., peak load) are reduced to conserve power and/or energy which is detrimental to performance and/or inconvenient to the user. In such a situation, the host mobile device 110 can supplement the power and capacity of its own battery with the battery 170 of the mobile device cover 100, thereby avoiding the power-save mode of the processor of the host mobile device 110 or vice versa. Accordingly, the processors in the host mobile device 110 can continue to operate at normal operation speeds and load capacities. Further, by supplementing power and capacity of the host mobile device 100, the battery 170 of the mobile device cover and the battery of the host mobile device 110 can be used to power a turbo mode in the processor of the host mobile device 110 or vice versa. For example, in turbo mode, the processor (e.g., a central processor, graphics processor, general processor, dedicated processor, etc.) of the host mobile device 110 can operate at one or more of the following: a higher voltage, a higher current, a higher power, a higher load capacity, and/or a higher clock speed than during normal operation. During turbo mode, the host mobile device 110 and/or the mobile device cover 100 can operate with greater performance and can perform more processor-intensive applications.

In some embodiments, when the host mobile device 110 is electrically connected to the mobile device cover 100 (e.g., when the host mobile device 110 has been inserted into the mobile device cover 110) and the mobile device cover 100 is plugged into a wall outlet, for example, the battery 170 of the mobile device cover 100 and the battery of the host mobile device 110 charge at the same time. In some embodiments, the battery of the host mobile device 110 charges without a decrease in charge speed even when the host mobile device 110 and the mobile device cover 100 are charged at the same time via, for example, the electrical connection (e.g., via a port 147) of the mobile device cover 100 to the wall plug, or a wireless charging station.

FIG. 1D shows an exploded side perspective view of an embodiment of the mobile device cover 100 according to the present disclosure. In some embodiments, the circuitry 150 can be embedded in the mobile device cover 100. In some embodiments, the circuitry 150 may include, for example, one or more circuit boards 150 a including, for example, one or more of the following: one or more processors, circuit elements or components, an integrated circuit, an integrated circuit chip, a system on a chip, etc. The circuitry 150 may also include, for example, one or more sensors 150 b (e.g., an audio sensor, a signal sensor, an optical sensor, a wireless signal sensor, a wireless receiver, a wireless transceiver, an electrical sensor, a power sensor, a battery sensor, an electromagnetic sensor, a vibration sensor, gyroscope sensor, iris scanner, fingerprint sensor, accelerometer, proximity sensor, barometer, hear rate sensor, a biometric sensor, etc.).

Some embodiments provide that a mobile application can be downloaded onto the host mobile device 110 to provide a graphical user interface that can be used, for example, to control the mobile device cover 100. The mobile application can run on the host mobile device 110 and/or the mobile device cover 100. Further, the mobile application can be automatically or manually updated, upgraded, modified, replaced, overwritten, supplemented, etc. via a wireless or wired connection.

FIGS. 3 and 4 show an exemplary launch screen page and an exemplary front page according to an embodiment of the present disclosure. The mobile application can be represented as an icon on the display of host mobile device 110 and/or the mobile device cover 100. When the icon is selected, the mobile application runs on the host mobile device 110 and a launch page as shown in FIG. 3 is displayed by the host mobile device 110. Subsequently, a front page as shown in FIG. 4 is displayed. While the front page is being displayed, the mobile application attempts to wirelessly and/or wiredly connect the host mobile device 110 and the mobile device cover 100 according to an embodiment of the present disclosure. In one embodiment, the mobile application attempts to connect and pair the mobile device cover 100 and the host mobile device 110, which are both Bluetooth-enabled. If unsuccessful, the mobile application according to some embodiments attempts to establish an alternative connection such as, for example, a USB-type connection, WiFi connection, Zigbee connection, cellular connection, etc.

FIG. 5 shows an exemplary home page according to an embodiment of the present disclosure. Upon successful connection and pairing, the mobile application displays a home page as shown in FIG. 5 . The home page provides a graphical user interface by which the user can navigate the mobile application. Referring to FIG. 5 , the home page includes icons or hyperlinks to a phone page, a message page, an email page, a notification for the application page, a lighting for contacts page, a battery page, a lighting page, a back design page, and a settings page. In addition, the home page provides for controlling a brightness of a display and/or a volume for a speaker for the mobile device cover 100 and/or the host mobile device 110.

In some embodiments, the phone page, the message page, and the email page provide the user with the ability to set up a particular lightshow (e.g., light pattern, animated light pattern, video, etc.), a particular icon (e.g., icon, emoji, graphical element, etc.), and/or a particular text (e.g., scrolling text) to be displayed for a particular contact and/or a particular type of communication (e.g., phone, message, email, etc.) for that particular contact on a contact list stored in the host mobile device 110.

In some embodiments, the notifications for application page sets up the type of notification (e.g., an alert, no alert, scroll contents of notification, icon, light show, etc.) for other mobile applications (e.g., eBay, calendar, clock, Amazon, Facebook, Snapchat, Instagram, LinkedIn, etc.).

Referring to FIG. 6 , the current battery percentage is shown for the mobile device cover 100 and the host mobile device 110. For example, the mobile device cover 100 has a battery charge of 55%; the host mobile device 110 (e.g., a mobile phone) has a battery charge of 98%. When fully charged, the battery charge indicates 100%. The mobile device cover 100 can also include, for example, four battery indication LEDs to indicate battery charge. For example, if the battery 170 of the mobile device cover 100 is fully charged, then the four battery indication LEDs can be lit; if the battery 170 of the mobile device cover 100 is only half charged, then two of the four battery indication LEDs can be lit; etc. In some embodiments, when either the host mobile device 110 or the mobile device cover 100 is charging, a charging icon overlays the battery figure. In some embodiments, when either the host mobile device 110 or the mobile device cover 100 is charging, the battery indication LEDs can portray this to the user (for example, a pattern, strobe, etc.). The charging icon can overlay the battery figure or the respective portion of the battery figure corresponding to the battery that is being charged (e.g., the battery 170 of the mobile device cover 100 and/or the battery of the host mobile device). The battery page also allows the user to turn on or off the automatic charging of the selected battery (e.g., the battery 170 of the mobile device cover 100 and/or the battery of the host mobile device). In some embodiments, this can be achieved by a single touch of the page displayed on a graphical user interface of the host mobile device 110 or the mobile device cover 100, or by actuating a button on the host mobile device 110 or the mobile device cover 100.

In some embodiments, the battery page allows the users to determine how the battery of the host mobile device 110 and the battery of the mobile device cover 100 interact. The host mobile device 110 and the mobile device cover 100 comprise sensors that detect voltage, current, and/or power supply and report the detected voltage, current, and/or power supply to one or more processors or other circuitry in the host mobile device 110 and/or the mobile device cover 100. The sensors can be used to detect the amount of charge or power remaining in the batteries of the host mobile device 110 and/or the mobile device cover 100. This battery charge information, for example, can be shown on the battery page. Further, one or more processors or other hardware in the host mobile device 110 and/or the mobile device cover 100 can receive battery charge information, for example, for the batteries via the sensors. The battery charge information can then be sent to one or both of the host mobile device 110 and the mobile device cover 100. The one or more processors or other hardware in the mobile device cover 100, for example, can cause the batteries in the mobile device cover 100 and/or the host mobile device 110 to charge one another. Similarly, the one or more processors or other hardware in the host mobile device 110 can cause the batteries in the host mobile device 110 and/or the mobile device cover 100 to charge one another. Such charging configurations can be set up using the battery page. In addition, the battery page or variations thereof can be used to implement and illustrate the embodiments relating to battery charging disclosed herein. In some embodiments, the battery page or variations thereof can be displayed on the host mobile device 110 and/or the mobile device cover 100. Graphical or actual buttons on the host mobile device 110 and/or the mobile device cover 100 can be used to set up the battery charging configuration. In one embodiment, a single physical button on the host mobile device 110 and/or the mobile device cover 100 can be used to set up the battery charging configuration.

In some embodiments, the user can set auto charging parameters in a process 300 in which the mobile device cover 100 charges the host mobile device 110 as shown in an exemplary flowchart in FIG. 7 . Referring to FIG. 7 , a user can manually set or automatically set (e.g., automatically set to preset or default values) a start auto charging parameter X (e.g., 25%) in step 310 and a stop auto charging parameter Y (e.g., 80%) in step 320. Graphical or physical buttons can be provided to enter or incrementally increase or decrease the charging parameters, or to enter numerical values. The charging parameters are sent to the mobile device cover 100 (or the host mobile device 110) as a signal (e.g., a digital wireless or wired signal). In query 330, if the battery percentage of the battery of the host mobile device 110 is greater than 25%, then query 330 is repeated. In query 330, if the battery percentage of the battery of the host mobile device drops to or below 25%, then the battery 170 of the mobile device cover 100 automatically charges the battery of the host mobile device 110 in step 340. In query 350, if the battery percentage of the battery of the host mobile device 110 is less than 80%, then the battery 170 of the mobile device cover 100 automatically charges the battery of the mobile host device 110 in step 340. In query 350, if the battery percentage of the battery of the host mobile device 110 reaches or exceeds 80%, then the charging of the battery of the host mobile device 110 automatically stops in step 360. The process 300 returns to query 330, and the charging of the battery of the host mobile device 110 does not automatically start again in step 340 until the battery percentage of the battery of host mobile device 110 reaches or drops below 25%. In some embodiments, the user can set a battery percentage of the battery 170 of the mobile device cover100 below which the battery 170 of the mobile device cover 100 automatically stops charging the battery of the host mobile device 110.

In some embodiments, the user can set auto charging parameters in a process 370 in which the host mobile device 110 charges the mobile device cover 100 as shown in an exemplary flowchart in FIG. 8 . Referring to FIG. 8 , a user can manually or automatically set (e.g., automatically set to preset or default values) a start auto charging parameter R (e.g., 30%) and a stop auto charging parameter S (e.g., 60%). Graphical or physical buttons can be provided to enter or incrementally increase or decrease the charging parameters, or to enter numerical values. The charging parameters are sent to the mobile device cover 100 (or the host mobile device 110) as a signal (e.g., a digital wireless or wired signal). In query 400, if the battery percentage of the battery 170 of the mobile device cover 100 is greater than 30%, then query 400 is repeated. In query 400, if the battery percentage of the battery 170 of the mobile device cover 100 drops to or below 30%, then the battery of the host mobile device 110 automatically charges the battery 170 of the mobile device cover 100 in step 410. In query 420, if the battery percentage of the battery 170 of the mobile device cover 100 is less than 60%, then the battery of host mobile device 110 automatically charges the battery 170 of the mobile device cover 100 in step 410. In query 420, if the battery percentage of the battery 170 of the mobile device cover 100 reaches or exceeds 60%, then the charging of the battery 170 of the mobile device cover 100 automatically stops. The process 370 returns to query 400, and the charging of the battery 170 of the mobile device cover 100 does not automatically start again in step 410 until the battery percentage of the battery 170 of mobile device cover 100 reaches or drops below 30%. In some embodiments, the user can set a battery percentage of the battery of the host mobile device 110 below which the battery of the host mobile device 110 automatically stops charging the battery 170 of the mobile device cover 100.

Some embodiments contemplate implementing processes for charging one or both of the battery of the host mobile device 110 and the battery 170 of the mobile device cover 100 according to battery percentages, for example.

In some embodiments, the battery page allows the user to manually select one battery to charge the other and to initiate charging. For example, the user can select the battery of the host mobile device 110 to charge the battery 170 of the mobile device cover 100, or vice versa. In some embodiments, charging can be toggled on until toggled off, and/or can be timed. Battery charging parameters can also be set by the user during manual charging that determine when the manually-initiated charging automatically stops. For example, the manually-initiated charging can automatically stop if the battery being charged reaches or exceeds a particular battery percentage, or the battery being used as a charging source reaches or drops below a threshold battery percentage.

In some embodiments, the battery page allows the user to supplement the power supply of the host mobile device 110 or the mobile device cover 100. For example, as rechargeable batteries age, they are unable to provide the voltage and/or current as when the battery was new. This can affect the performance of the processor over time. If the voltage and/or current supplied by the battery is low enough, the processor can be forced to slow down as part of a power-save mode, which detrimentally affects the operation of the host mobile device 110, for example, and the operation of the applications running on the host mobile device 110. Accordingly, if the battery of the host mobile device 110 ages to the point that the processor needs to go into a power-save mode, some embodiments provide that the battery page can be used to manually or automatically supplement the battery of the host mobile device 110. The battery 170 of the mobile device cover 100 can supplement the current, voltage, and/or power provided by the battery of the host mobile device 110 so that the processor is fully powered and need not go into a power-save mode.

In some embodiments, even if the processor is not operating in a power-save mode, the battery page can be used to manually or automatically supplement the battery of the host mobile device 110 to cause the processor to run in a turbo-mode that is faster than its normal operation. In some embodiments, the host mobile device 110 may be operating too many I/O devices and may require additional power. The battery page can be used to manually or automatically supplement the battery of the host mobile device 110 so that the host mobile device 110 can drive even more I/O devices than it is currently capable of driving.

In some embodiments, the battery page displays battery energy as a percentage of the total energy of the batteries of the mobile device cover 100 and the host mobile device 110. For example, if the batteries of the mobile device cover 100 and the host mobile device 110 are fully charged and have the same charge capacity, the battery page would display a battery energy percentage of 50% for the mobile device cover 100 and a battery energy percentage of 50% for the host mobile device 110. If the mobile device cover 100 has a battery 170 that is fully charged and has twice the charge capacity of the battery of the host mobile device 110, then the battery page would display a battery energy percentage of 67% for the mobile device cover 100 and a battery energy percentage of 33% for the host mobile device 110.

In some embodiments, the user can set auto charging parameters for the mobile device cover 100 to charge the host mobile device 110 based on battery energy percentages as shown in an exemplary flowchart in FIG. 9 . Referring to FIG. 9 , a user can manually set or automatically set (e.g., automatically set to preset or default values) a start auto charging parameter U (e.g., 5%) in step 450 and a stop auto charging parameter V (e.g., 25%) in step 460. Graphical or physical buttons can be provided to enter or incrementally increase or decrease the charging parameters, or to enter numerical values. The charging parameters are sent to the mobile device cover 100 (or the host mobile device 110) as a signal (e.g., a digital wireless or wired signal). In query 470, if the battery energy percentage of the host mobile device 110 is above 5%, then query 470 is repeated. In query 470, if the battery energy percentage of the battery of the host mobile device 110 drops to or below 5%, then the battery 170 of the mobile device cover 100 automatically charges the battery of the host mobile device 110 in step 480. In query 490, if the battery energy percentage of the battery of the host mobile device 110 is less than 25%, then the battery 170 of the mobile device cover 100 automatically charges the battery of the host mobile device 110 in step 480. In query 490, if the battery energy percentage of the battery of the host mobile device 110 reaches or exceeds 25%, then the charging of the battery of the host mobile device 110 automatically stops in step 500. The process 440 returns to query 470, and the charging of the battery of the host mobile device 110 does not automatically start again in step 480 until the battery energy percentage of the battery of host mobile device 110 reaches or drops below 5%. Thus, the user is managing the relative battery energy of one battery with respect to the other, or the distribution of total battery energy between the two batteries.

A similar process is also contemplated by some embodiments for charging the battery 170 of the mobile device cover 100 instead of the battery of the host mobile device 100 as in FIG. 9 . Some embodiments contemplate implementing processes for charging one or both of the battery of the host mobile device 110 and the battery 170 of the mobile device cover 100 according to battery energy percentages, for example.

FIG. 10 shows a mobile device/phone cover 1001 and a mobile device/phone 1011 according to an exemplary embodiment of the present disclosure. The mobile phone cover 1001 may be positioned around the mobile phone 1011 to provide protection as well as a battery backup.

The mobile phone cover 1001 may comprise a battery 1003, one or more processors (not shown), a charging interface 1005, a charging circuit 1007, and an interface 1009 for coupling to the mobile phone 1011. The mobile device/phone 1011 may comprise a battery 1013, a charging interface 1015, a charging circuit (not shown) and one or more processors 1017.

The charging interface 1005 of the cover 1001 may be selectively and operably coupled, via the cover charging circuit 1007, to an external power source 1019, the cover battery 1003, and the mobile phone battery 1013. The cover charging circuit 1007 may also operably couple the mobile phone battery 1013 to the cover battery 1003.

The one or more processors 1017 may selectively couple the cover battery 1003 to the charging interface 1005 according to a passthrough charging parameter. For example, the one or more processors 1017 may be configured to provide a user interface as shown in the exemplary battery charging page of FIG. 11 . The passthrough charging parameter selection may be via a graphical user interface as illustrated in FIG. 11 . Alternatively, the passthrough charging parameter may be selected via the mobile phone cover. For example, a user may activate the cover charging circuit 1007 via the mobile phone cover without accessing the mobile phone or any mobile application.

Turning back to FIG. 10 . When the passthrough charging parameter is selected, the mobile phone battery 1013 is operably coupled to the charging interface 1005 and the cover battery 1003 is decoupled from the charging interface. When the passthrough charging parameter is deselected, the mobile phone battery 1013 and the cover battery 1003 are both operably coupled to the charging interface 1005.

The one or more processors 1017 or cover charging circuit 1007 may be configured to generate a warning if a flow of charge to the charging interface is below a threshold. If the mobile phone battery 1013 and the cover battery 1003 are both operably coupled to the external power source 1019 via the charging interface 1005, the charging capability of the external power source 1019 may be split between the mobile phone battery 1013 and the cover battery 1003. A threshold of 2 amps, for example, may be set such that a warning is triggered if the external power source 1019 is unable to supply 2 amps. This warning may be an audible and/or visual warning on the mobile phone 1011 and/or the mobile phone cover 1001.

The one or more processors 1017 or cover charging circuit 1007 may be configured to prioritize between charging the mobile phone battery 1013 or the cover battery 1003 according to the flow of charge (e.g., amperage) to the charging interface 1005 being below a threshold. This prioritization may be selectable as shown in FIG. 12 . The illustrated “Smart Charge Priority” on the exemplary battery settings page of FIG. 12 shows that either the mobile phone battery 1013 or the cover battery 1003 may be selected, via a graphical user interface, to be charged first.
